APPARATUS FOR CHANGING THE POFITIONS OF HANKS 0F YARN ON DYEING-STICKS.

Specification of Letters Patent.

Patented June 20, 19148.

To all whom it may concern:

lie it known that I, Jacouns SorrLUMrr, a citizen of the Swiss Republic,residing at Brugg, Canton Aargau, Switzerland, have invented certain newand useful Improvements in Apparatus for Changing the Positions of HanksofYarn on Dyeing-Sticks, of which the following is a specification.

Yarn in 'hanks is dyed or bleached by suspending the hanks from sticksor rods which are laid across the dyeing tubs in such a manner that thehanks are partially immersed into the dye. To dye the hanks uniformlythroughout, the position of the same upon the sticks is changed, fromtime to time, so that at each change of position, that part of thehanks. situated above the surface of the dye, is dipped into the dye.

The object of the present invention is to improve the machines whichhave been used hitherto to perform automatically the abovementionedoperation of shifting the hanks of yarn. I attain this object by using ahank carrier consisting of two bars rigidly connected with each otherand by rotating the carrier alternately about the two parts in such amanner, that the upper bar always turns around the lower bar. The hanksof yarn follow the descending bar by their own weight without stretchingthe threads in a dangerous manner.

To accomplish these objects, my invention consists in the novel detailsof construction and in the combination, connection and arrangement ofparts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings forming part of this specification whereinlike numerals of reference indicate like parts: Figures 1 to 6 show acarrier for the hanks of yarn in several different positions. Fig. 7 isa sectional elevation of a machine for automatically turning thecarriers. Fig. 8 is another sectional elevation of the same machine.Figs. 9 to 14 illustrate diagrammatically the difierent positions of thehank carrier and of the hooks for turning said hank carrier. Fig. 15shows a modified construction of the machine in side elevation. Fig. 16is a front view of the machine shown in Fig. 15. Fig. 17 is another formof construction in front view, parts being in section. Fig. 18 is a sideview of the machine shown in Fig. 17. Fig. 19 is a side view of astationary machine for turning the hanks. Fig. 20 illustrates thismachine in front view, parts being in section and Figs. 21 to 23illustrate a clutch. Fig. 24 shows a device for opening the lifters.Fig. 25 is a detail View showing a portion of Fig. 24.

The hanks a are arranged on a carrier 7) comprising two parallel bars 3and 4: rigidly connected by two cross bars 1 and 2. One of the bars 3 issufliciently longer than the other bar t so that the carrier 7) may belaid transversely across the trough containing the liquid for thetreatment of the hanks a, while the other bar 1 is shorter so that itmay be arranged between the side walls of the trough. The distancebetween the bars 3 and 41 is considerably less than the length of thehanks a. The operation for shifting the hanks a, if performed by hand,is the following: The bar 3 is raised from the trough by two operatorsstanding on opposite sidcs of the trough and turn until the bar 4 isabove the trough. The bar 4: is now held by the two operators while thebar 3 is released, and. together with the hanks desccnds intotheposition shown in Fig. 3. During the descent of said bar 3, thethreads of the hanks cannot entangle and they are not submitted to anystress or friction so that the threads will not be unduly stretched ortorn. After having made one turn of 180 about the bar 4:, the carrier 7)is rotated for a second time by using bar 3 as the axis of rotation.That part of the hank which was previously resting on the bar 8 is nowbelow the level of the liquid after the carrier I) has performed twoturns. The carrier Z), which ultimately assumes the position shown inFig. 5 is then laid on the trough. The carrier 7) may be constructed asshown in Fi 6. 4 arranged parallel to each other in the cross bars 1 and2. On said cross bars 1 and 2 two studs 3 are fixed by means of whichthe carrier Z) may be laid over the trough. .By using the carrier 7)Fig. 6 the hanks a may be entirely immersed in the liquid.

The hank shifting machine illustrated in Figs. 7 and 8 comprises twoframes fixed to a common casing C. Said casing C is suspended from twoparallel shafts provided with running rollers at their ends. The runningrollers are guided upon rails 6 and 7 which are fixed above the trough.For the purpose of taking hold of the hank carriers at their ends, thereare pivotally mounted The hanks a are slid over two sticks 9 ill] 'graspthe upper bar 3 in each frame two lifting wheels with two liftersarranged diametrically opposite each other. Each lifter comprises tworo-- tatably mounted parts 12 and 12 which are held in normal positionby a spring. The parts of the lifters may be forced back by means ofguides 13 (Fig. 7) fixed on the said framesfor the purpose of permittingthe ends of the carrier Z) to enter the lifters. The lifting wheels 10are driven by a motor 1 1. The motor axleis geared to the lifting wheels10 by means of a spur wheel keyed to a shaft 16 which is connected witha shaft 19 by means of a toothed gear 17. The said shaft 19 is rotatablymounted in the two frames of the machine and carries two spur wheels 18which drive by means of an inter mediate wheel 11 the two pairs oflifting wheels 10 which are all rotated in the same direction.

If the gear 10 rotates fromthe position 2 shown in Fig. 2 1, the partastrikes against the guide 13 fixed to the frameof the ma chine at apoint 0. One ofthe levers 12 having'anose at co-acting for lifting astick 3 with a lever 12, is forced to swing out against the action ofthe spring (Z. The other lever 12, which does not have a nose at, restsimmovably in relation to gear 10 but lifts the stick 3 from the trough.As soon as the stick 3 rests well within the lever 12, the lever 12slides from the guide 13,

owing to the'tensio-n of the spring d. In the same mannerthe lever 12 isswung out in the top position shown in- Fig. 24: by means of a guide 2 1fixed to the frame of the machine.-

As soon as a hank carrier 1) has been lifted off the edge of the troughby the lifter on the lifting wheels 10, two hooks 23 of the hank carriernear its end. The lifters are now automatically opened by means of cams24. As soon as the carrier is held by the hooks 23 and the lifters havebeen opened, the lower bar 4 of the carrier 5 is caught by a pairofhooks fixed on a shaft'26 (Fig. 3). The hooks 25 are supported bycollars 26 and oscillated by the shafts 26 which are connected by theconnecting link 31 with a crank pin on the shaft 19 (Fig. 7). Themovement of the hooks 23 and 25 is such that the upper bar 3 is releasedby the hooks 23 as soon as the lower bar 4 is engaged by the hooks 25,so'that the carrier 5 makesa turn of about 180 about the bar 4:. Thehooks 25 swinging in the direction of the arrow shown in Fig.13 raisethe carrier Z), and the latter is laid upon two seats 32, provided ateach side of the machine. (See 7 and 8.) To prevent the carrier frompassing over the said seats 36 I arrange on each side of the trough alever 27, pivotally mounted in the frame of the machine (Figs,

7 and 8). The carrier resting on the seats 36 is now lifted for a secondtime by means of the second pair of lifters on each wheel 10. The saidsecond pair of lifters are automatically opened and move the lower bar4, while the upper bar 3 rests on the seats 36, in a circular pathwithout moving the carrier. The carrier is then laid transversely overthe trough.

The rotation of the motoaxle is further transmitted by means of the gear15, shaft 16 and toothed gearing 1S and 19 to a shaft 20. journaled inthe side wall of the casing U. On each side of the casing (l a spurwheel 21 is keyed on shaft 20, said spur wheel 21 engaging a rack. 22fixed to the rails 6 and 7. The direction of travel of the machine maybe reversed by reversing the direction of rotation of the motor axle orby any well known change gear. There may be arranged two sets of hooks23, 25, one set working while the machine travels in onedirection, whilethe other set works when the direction of travel is reversed. Moreover Imay, provide means to bring the hooks out of action for instance byuncoupling the shafts 26 from the driving gear. A suitable clutch forthis purpose is shown by way of example in Figs. 21 to 23. Theconnecting rod 31 is pivotally connected to a rocking lever 32 which isloosely mounted upon the shaft 26. Lever 32 is provided with an arm 34:which has an axially projecting arm The arm 35 projects into a recess 36in an arm 33 keyed to said shaft 26. Between the rocking lever 32 andthe lever 34 a pawl 37 is rotatably mounted. The said pawl 37 isprovided with a lug 38 which together with the arm 35 completely fillsthe recess 36of the arm The pawl 37 is controlled by a weight whichtends thrust the lug 33 into the recess 36. If the pawl 38 is not in therecess 36 the lever 32 can rock without taking the leyer 33 and theshaft 26 along.

The throwing into and out of operation of the pawl 33 and consequentlythe rocking of the hooks 23 and 25 is effected by a double-armed lever41 (Fig. 7), pivotally mounted in the casing C. One end of the lever 4.1 projects into the path of a lag -l-,() on the pawl 37 while the otherend carries a roller running on a cam which is keyed on a. shaft. Thesaid shaft is rotatably mounted in the casing and may be rotated by handor automatically by means of suitable devices which come to action assoon as the machine changes its direction of travel.

The machine shown in Figs. 15 and 16 works in essentially the samemanner as described with reference to the machine shown in Figs. 7 andS. It differs from the machine described above in that the machine isnot suspended on rails but runs on rails fixed to the floor. The machineis double acting, and it is adapted to turn the hank carriers of twotroughs standing parallel to the direction oftravel of the machine. Thecarriers Z) are held on one end only by means of lifters arranged onlifting wheels 613 of which two are provided for each trough. Eachlifter comprises two parts 1t slidable on each other and actuated bydouble armed lever 46, in such amanner that the carriers areautomatically grasped and released. The rocking motion of the hooks 23and 25 is imparted by a system of lovers actuated by a cam. Thefunctions of the hooks 23 and 25 are precisely the same as describedabove with reference to Figs. 9 and 12.

The machine shown in F 17 and 13 comprises a casing C suspended by meansof two pairs of rollers 80, 81 running on rails 82. In the casing C anelectric motor M is mounted and drives by means of two gears a shaft 85ournaled in the side walls of the casing C. Exterior to the side wallsof ms ing 0, the shaft 85 is provided with two spur wheels 87 engagingracks 89 fixed to the rails 82. The gearing comprises a clutch 90 and ashaft 91 which project on both sides from the casing (1. Near each ofthe ends of shaft 91, outside the casing C, a spur wheel 93, and a disk94 are secured. The said spur wheels 93 drive the lifting wheels 95 byany well known means (not shown). The lifting wheels 95 are rotatablymounted in frames 90 secured to the casing C. Each of the lifting wheels95 carries a lifting ring 97 having at its cir cumference teeth 98 atregular distances apart from each other. The arrangen'ient of thelifting gear is such that the teeth 93 lift the carrier 7) off the edgeof the trough T. Above the lifting wheels 95 there is 1'0- tatablymounted in bearings a shaft 100 which receives a rocking motion from acrank pin on the said disk 9&1 by means of connecting rods 101 andlevers 102. A clutch, similar to that shown in Figs. 21 to 23, anddescribed with reference thereto, may be arranged on said shaft 100. Theshaft 100 is connected with a shaft 100 by means of a lever 107. Toshaft 100 two hooks are keyed adapted to hold the carriers 7). Parallelto the shaft 106 there is arranged another rocking shaft 100 on which apair of hooks 110 is secured. Shaft 106 receives its rocking motion fromthe shaft 100 by means of a system of levers not shown in the drawings.Below the hooks 110, 110' and above the lifting wheels 97 twooscillating arms 111 are keyed to a shaft 112 mounted in bearings of theframe 96. Each oscillating arm 111 is provided on its free end with aguide piece 113 by means of which the carrier 7) may be lifted off thelifting rings 97. The oscillating arm 111 is raised by a lever 115 whichis pivoted at 116 and which is raised by means of a cam 117 secured tothe shaft 91. Lever 115 is provided at its free end with a stud withwhich one of two upright hooks 118 may come into engagement. The saidhooks 118 are steered by lever 119 from the shafts 100 in such a mannerthat the oscillating arms work in conjunction either with the shaft 100or with the shaft 106. The movements of the parts 110 and 113 are suchthat the oscillating arms 111 lift a carrier 6 from the lifting ring assoon as the hook 110 has descended into its lowest position and passbehind the carrier 6 and immediately before the hook 110 reverses itsaction. The hooks 110 catch on the upward movement the lower bar 1; ofthe hand carrier 1) and as soon as it held firmly the upper bar 4: fallsdown, the carrier Z) making a turn of 130 about the lower bar 1. Thelatter is now deposited on two movable seats 11S arranged at the sidesof of the lifting rings 97. The bar 4 is now liberated by the said hooks110 and the car rier t performs a second turn of 180 about the bar 3.The carrier 7) falls from the seats 118 by its own weight and isdeposited upon the edge of the trough. While the machine is traveling inone direction the hooks 110 are in operation while by reversing thedirection of travel the other pair of hooks 110 come to action. Ofcourse both pairs of hooks can be brought out of action.

In some instances it is desirable to lift all the carriers 7) togetherfrom the edge of the trough. To achieve this result I employ a liftingappliance comprising two pairs of carriages 120 arranged on both sidesof the trough. These carriages are guided on vertical. rails 121 securedto the casing C. The carriages on one side of the trough are adapted tocarry a bar 122 which when rising lifts the carrier 7). To raise thecarriage 120 and the bars 122 I make use of the motor M which drives theshafts 125 by the intermediary of a toothed gearing. To said shaft 1.25two drums 127 are secured to which ropes 130 are attached. These ropes130 are guided over guide pulleys 120 and the ends of the ropes 130 aresecured to the bars 122. The lifting appliance comprises a brake 131,and a device for disconnecting the lifting appliance from the rotor M ofknown design, but not illustrated.

In Figs. 19 and 20 a stationary machine is shown diagrammatically. Thetrough T is mounted upon a carrier running on rails 130. On both sidesof the trough T frames 137 are secured to bases 138. The two frames 137support a driving shaft 139, and two spur wheels 141, 1412 looselymounted, either of which may be connected with the shaft 139 by means ofa clutch 143 axially movable but not rotatably mounted on the shaft 139.The spur wheel 1 11 is in mesh with a wheel 14: 1 on a shaft 145 and thespur wheel 1412 engages a transport wheel 147 meshing with a gear 1 16keyed 25 oawl en 'a in a toothed ear on shaft 153.

12 b b b to said shaft 145. The direction of rotation hooks 154 adaptedto turn the carrier 7) in the manner described above. The shafts 153have a rocking motion which is imparted to them by connecting rods 155from the gear'151. Upon the shafts 153 clutches are arranged by means ofwhich said shafts may be thrown out of connection with the driving gear151. Special means are shown for. the purpose of bringing the hooks 154,

which are not to work, to a standstill. On each side of thetroughftlwreis arranged a horizontal bar 160 which is mounted on two levers 161,162. To the bar 160 a cam plate 163 is secured which acts upon a doublearm lever 166. The latter is provided with a If the bar 160 is moved tothe left in Fig. 19 the lever 166 will move the said toothed wheel onshaft 153 for one tooth and hold the shaft in a fixed position wherebythe hooks 154 are out of way. The bar 160 is automatically shifted uponeach reversal of the direction of travel of the machine. The lever 162is abell-crank lever, one arm of which is connected bya rod 168 to anarm 169 of a shaft 170 which operate the clutch 143 by means of bevelgears.

' The carriers Z) are lifted by the wheels150 and then turned by thehooks 154 which get hold of the lower bar of the carrier laid on thelifting wheel. After the carrier has been turned 180 the bar 4 ofthecarrier is laid on the said bars 160. The hooks 154 rceede and thecarrier Z) will fall down making another turn of 180 whereafter thecarrier is deposited upon the edge of the trough. The carriage 135 maybe provided with a rack and a train of spur wheels may be arranged inone of the frames adapted to engage said rack.

I do not limit my invention to the means for lifting the carriers or thedriving gears for the different organs in the machine, but

What I claim is:

1. A machine for automatically shifting hanks of yarn comprising incombination a trough, carriers having two pivots, means to lift saidcarriers separately, and means to turn the said carriers about the lowerpivots.

2. A machine for automatically shifting hanks of yarn comprising incombination a trough, carriers for the hanks comprising two parallelrods connected with each other, two pivots on said carrier, rotatinglifting Wheels, hooks adapted to engage the lower pivots of saidcarriers, and means to change the relative position of lifting wheel andtrough.

3. A machine for automatically shifting hanks of yarn comprising incombination a fixed trough, carriers comprising two parallel rods,connected with mch other, rotating lifting wheels one on each side ofthe trough, swinging hooks, means to lift the carriers from the liftingwheel into the path ofthe hooks, and means to move the machinerelatively to the trough.

In testimony whereof I a'liix my signature in presence of two witnesses.
